Computational Chemistry

This corrected second edition contains new material which includes solvent effects, the treatment of singlet diradicals, and the fundamentals of computaional chemistry. "Computational Chemistry: Introduction to the Theory and Applications of Molecular and Quantum Mechanics" is an invaluable tool for teaching and researchers alike. The book provides an overview of the field, explains the basic underlying theory at a meaningful level that is not beyond beginners, and it gives numerous comparisons of different methods with one another and with experiment.

The following concepts are illustrated and their possibilities and limitations are given:

• potential energy surfaces;
• simple and extended Hueckel methods;
• ab initio, AM1 and related semiempirical methods;

• density functional theory (DFT).

  Topics are placed in a historical context, adding interest to them and removing much of their apparently arbitrary aspect. The large number of references, to all significant topics mentioned, should make this book useful not only to undergraduates but also to graduate students and academic and industrial researchers.

The second edition of this popular textbook takes a pedagogical approach Includes questions (classed as 'harder' and 'easier') which are aimed at students of varying abilities The only textbook on this subject to genuinely cover the basics Each chapter is presented with an initial historical overview thus enlightening students and guiding them away from the usual 'dry' presentation of facts. A must for computational chemistry university lecturers Includes supplementary material: sn.pub/extras

Auteur
Prof. Dr. E.G. Lewars Errol G. Lewars obtained his Ph.D. with Peter Yates at the University of Toronto, synthesizing unnatural products, then worked with R. B. Woodward at Harvard on vitamin B12, and with J. F. King at the University of Western Ontario on organosulfur compounds. He is currently Professor of Chemistry at Trent University, Peterborough, Ontario, Canada. The development of methods which provided a realistic assessment of the properties of unknown compounds induced him to move into computational chemistry. His work Computational Chemistry. An Introduction to the Theory and Applications of Molecular and Quantum Mechanics (published by Kluwer, 2003) was named as CHOICE magazine's "Outstanding Academic Title" of 2004.

Texte du rabat

The second edition of this popular textbook has been revised to improve explanations and to add topics which were not featured in the first edition. It also contains extended, updated examples and references. The questions (the hallmark of a genuine textbook) at the end of each chapter fall into two classes: to test and reinforce the reader's understanding, and to encourage deeper thought. As in the first edition, all pivotal statements and examples are supported by original literature references, and these have been updated to 2009 and 2010. Many calculations included by the author serve to illustrate and to show the scope of various methods.

The main methodologies, e.g molecular mechanics, ab initio, semiempirical, and density functional theory (DFT), are introduced in a historical context (but without glossing over scientific detail) because the author believes that a scientific text should also be a humane exposition and not a collection of recipes.

This textbook is intended for undergraduate and graduate students working in computational and theoretical chemistry courses and for researchers in universities and industry to whom computational chemistry may be useful. It may be used for self-study or with an instructor.

"Errol Lewars has done it again. The author of "Modeling Marvels: Computational Anticipation of Novel Molecules" has written a new edition of another of his highly interesting and informative books, one that interleaves and interweaves rigorous theory, computational protocol, dare I say "classical chemistry", and biographical snapshots. Both the novice and practitioner will find much to enjoy and be educated by Lewars' decision to include easier questions, harder questions and answers that accompany the text." (Prof. Joel F. Liebman, University of Maryland, Baltimore County, UMBC, USA)
